It carries a 0.100" (2.54 mm) pitch on both the mating interface and row spacing, making it a direct drop-in for standard 0.100-inch grid prototyping boards and perfboards. The contact finish tells the real duty story: the mating interface carries 30.0 µ" (0.76 µm) of gold GXT™ plating, while the solder/post side gets a 39.4 µ" (1.00 µm) tin finish. That gold-on-the-mating-side spec is what gives this header its repeated-mating-cycle capability — it is not a one-and-done press-in pin. The press-fit tail option (alongside solder) means this header can be assembled into a backplane without a wave solder step, though the through-hole mounting keeps it compatible with standard soldering processes as well.
Where This Sits in the BERGSTIK Series
The 93690-103-32LF is a 32-position variant of the BERGSTIK breakaway family, which spans from 2 to 36 positions in a dual-row layout. The breakaway feature — scored pin strips that snap to the required position count — means the 32-position version is the full strip; no snapping needed if your BOM calls for 32 circuits. The 0.100" pitch and 0.100" insulation height are series constants, so the footprint and stack height are identical across all 93690-series members. The key differentiator here is the gold GXT mating finish: the 93690 series also offers a tin-plate option for cost-sensitive, low-cycle applications, but the 30.0 µ" gold on this variant supports higher mating cycle counts and better corrosion resistance in humid or lightly aggressive environments.
The 0.100" pitch and 0.100" row spacing place the pins on a standard 0.1-inch grid, so this header fits any 0.1-inch perfboard or protoboard with 0.042-inch or larger holes. The 0.177" (4.50 mm) post length is sized for standard 1.6 mm PCBs with room for a solder fillet on the bottom side. It mates with any 0.100-inch pitch female socket header or IDC receptacle — the BERGSTIK series does not enforce a proprietary mating half, so the choice of receptacle is driven by your wire termination (crimp, IDC, or solder cup). For a wire-to-board connection, pair it with a standard 0.100-inch pitch crimp housing and terminals; for a board-to-board stack, use a matching female breakaway or box header.
